125-200cc Scalvini - 2004 CR125

Can't argue with that. I was very disappointed with the way it mounted up but it was easy enough to fix. Complaining about it wasn't going to fix it and I was not confident that a replacement was going to fit any better. Don't care for the plated finish on the PC/FMF pipes.

Lol, now I'm worried about crunching the pipe!

I'm sorry but a stinger? I don't see it. Do you mean tailpipe?.

Man that is a nice machine - wouldn't want to ride it

On a side note I have noticed the removal of the standard pipe on the later 09 frame is a lot harder than the older frame. The end hits on suspension reservoir - I think I may have to remove the subframe just to get it off

The pipe inserted in the end of the chamber is the stinger, right? The depth inserted is part of the tuning I thought.

From what i've learned the stinger should be located at the end of the reflector. The angle of entry beeing
The Same as the reflector. A stinger has a diameter to suit the power of your bike after this sertain diameter it gets bigger and enters into the tailpipe. The tailpipe should be larger then the stinger diameter and has no other function to the exhaust then to guide gasses to th exit. A muffer should be larger than a stinger and works best if they ar not stuffed tight with damper material.

This is what i know about slingers.

I also have learned that an exhaust from a 200cc bike will never give the power than a calculated pipe will give on a 125.

Just what i know and don't pretend to know it all.

That can happen. Ofcourse a change can make a big improvement. Then your lucky
